invention relates to a' connecused in connection with telephones or in other whereon'e end'of the from place to place and has for an object to provide an article of this character providing a'swivel connection between the various sections of'the'wire whereby to prevent the twisting and entangling m of the-same.

The-present ten for electric wire electrical appliances, electrical connection wire is moved about A further object of the invention is to pro-- vide an article of this character of-simple, compact'and practical construction which provides a safe means forconnecting the adjacent ends of the wire'without'danger of causing accidental contact between the op-.

osed wi'res so as to prevent short circuiting' thereof, which enables the respective ends of Y the wire to-be easily, quickly and securely attached in position thereto which is neat and attractivein appearance, sive to' manufacture and otherwise well adapted for the purposes is intended. T

-Other objects 'and advantages reside in the special construction and combination of the various elements comprising the invention, reference being had to the accompanying drawings forming apart hereof, wherein; Figure 1 is a longitudinal sectional view through the connecter, Figure 2 is a transverse sectional view taken substantially along 'a line 22 of Figure 1, V

Referring now to the drawing in detail, the invention comprises a tubular, sectional connecter housing composed of an intermediatesection 5 internally threaded at each end for threadedly receiving end sections 6. Each 60 of the sections 5 and 6 is formed of insulation nnw HAMPSHIRE;

opening in the wall of the intermediate section whereby to secure the collar against relative movement with respect to said section.

.The head of the screw 9 is countersunk in a recess 10 formed in the outer surface of the intermediate section 5.

Within the collar 7 is fitted a sleeve 11 arranged for relative rotary mojvement therebetwen. The collar 7 and sleeve 11 are constructed of conductor material adapted through their contacting relation to prbvide an electrical connection between the wires 12 and 13 extending through the opposite ends of the connecter housing, the end of the wire 12 being attached to one end of an arm 14 by means of its screw 15, the opposite end of said arm being interposed between the boss 8 and the inner wall of the intermediate section 5 and retained in position by means of the screw 9, the end of the wire 13 being attached 'to an ear 16, formed on the end of the sleeve 11 and secured thereto by means of a screw 17. I

T -e flange 18 is formed on the outer periphery of the sleeve 11 at the end thereof adjacent the ear 16 adapted to abut the edge limit the inward movement of such end of the sleeve.

The. socket member 19 is disposed in the sleeve 11 andretained in spaced relation from the wall of the sleeve by means of a section of insulation 20 said socket member and sleeve being assembled for rotary movement as a unit preferably by applying the porcelain thereto while in its plastic state and perm1t ting the'same to set with the parts in their assembled relation as illustrated in Figure 1 of the drawing.

" The socket member 19 is provided with a bore extending longitudinally therethrough, terial having a collar secured therein and an one end of the bore being of a relatively enassembly rotatably mounted in the c lar nd larged area as shown at 21 and internally providing a pair of separate conductor el ethreaded whereby to receive a threaded plug ments insulatedfrom each other,-one of sand 22 having a screw 23 thrcadedly introduced elements comprlslng ar tatable sleeve disin its outer end for attaching one end of a posed within the collar in contacting relation Wire 24 to the plug.
